 # Statement on security
 
 At its core, OpenProject is an open-source software that is [developed and published on GitHub](https://github.com/opf/openproject). Every change to the OpenProject code base ends up in an open repository accessible to everyone. This results in a transparent software where every commit can be traced back to the contributor.
